After careful consideration of similar apps, I chose this, which was a SAD mistake. Had about 30 or 40 tabs open wishing to save. I ran the app and it blew away all my open tabs, saving only about 7. I know exactly why, and you should really make this clear moving forward. Newer versions of Firefox, don't automatically load all saved tabs at start up. This is to save memory and resources and speed up the browser. I knew this before running the app, but thought I'd give it a shot anyhow, knowing that I'd likely need to make active all the tabs currently "asleep" in my browser, and run the app again. I figured worst case scenario it would just not open those tabs in a sleep state. Wrong !!! As I said above, it opened 7 tabs, and deleted the entire rest... Lots of research I had done on various subjects. Why don't you warn people of this issue? In reviewing similar apps, they mention just this. Your neglect in doing so cost me the loss of much-needed information... you're obviously aware of this issue, as it's mentioned several times in the reviews. Sorry man, but given that, this is beyond neglect, this approaches, dare I say, utter ignorance. Unfortunately, I neglected to read the reviews before installing. Bummer... Looks like well written software from the results I got, but unfortunately, poorly implemented to the public.

It is a most useful extension, i have it on windows and works perfectly, but on android it has some flows: At first, it saves only some of the opened tabs and permanently closes the rest. After some experiments i found out that it does not save the tabs that you have opened in background and not visited, or the tabs that you have not visited after opening the browser. If there is some settings that could fix it, some instructions on this matter from the developers would be very useful. The second annoying thing is that you can not choose whether or not, preferably not but unfortunately not an option, to open the onetab page automatically on a new tab when you open the browser first time after having terminated the app. When the app still runs on the background and you reopen it it does not open the onetab homepage tab. At least i have not found any kind of settings like on the windows version, if someone knows something more please share. If there is a way to overcome these flaws please state it, if not it would be nice to consider fixing them. This is a very useful extension and deserves the perfection, like the windows version..
